Expected action of type :update, but :destroy is of type :destroy

Dear community,

I’ve set up AshAdmin and upon applying the delete action on my resource I get the following error:

** (ArgumentError) Expected action of type :update, but :destroy is of type :destroy

I’ve done a thorough search of the forum and elsewhere (not Discord though). Look, I’m sure I’m “holding it wrong” but I really haven’t been able to find this issue documented, let alone any solution to it.

Does this make sense to anyone?

Any help would truly be appreciated.

This looks like a bug in ash admin internals actually :sob: don’t think you’re doing anything wrong at all. I’ll take a look later today.

Phew, then it’s not just me (perhaps) :face_exhaling:

Thanks for taking the time to comment. I’ll send you an invite as a collaborator on a repo that reproduces the issue.

Thanks for an amazing job on Ash!

Thank you for the reproduction :slight_smile: I’ve pushed a fix up, and published new versions of ash_admin and ash_phoenix. You’ll also need to update phoenix_html to ~> 4.0 to use the latest versions of those packages.
